Kilmainham Gaol

"Although more of a tourist attraction, I am including this Kilmainham Gaol in this guide as it is a key part of Irish history. Take the train or Uber back across the river for this quick stop; learn from experienced tour guides how the first jail to utilize a "single cell" philosophy worked, as well as its place in history with the IRA and deadly potato famine. Don't be scared to ask questions as the guides here are incredibly friendly and well-informed! Note that you will absolutely need a reservation for this tour. This is a popular attraction and spots fill up quickly!"

"Kilmainham Goal opened in 1796 to serve as the county goal. Tons & tons of people were imprisoned here, as well as executed. Sadly, it wasn’t just serial killers who took homage in Killmainham Goal. Men, women and children with petty thefts such as stealing food were locked up, as well. Since closing its doors in 1924, this prison is now open for the public to tour. To visit, you absolutely must book in advance."

"Prison museum where many of Ireland's political prisoners were incarcerated, tortured and executed."
